First off, this isn't a simple download, double click, and play kinda thing. Read the docs!
1.4 works well on my PPC mac with 10.3.9. Much thanks to those who put in the work to finally port this. It's not perfect, but it's certainly better than past releases.
btw, James... It says right there (twice) it requires PPC

Does not work on 10.5.1.
It also does not work on 10.4.11.
I wonder if this software is tested?
